`To all whom it may concern: Be it known that-I, HTRAM K. HAZLETT, ofthecity andpcounty of St. "Louis, State of Missouri, have invented. new anduseful Improvements in Bimgs, lof which the following is a full, clear,and exact description, reference being hereby had to the annexeddrawing' making part of this speciication, and to the letters ofreference thereon marked, in which- Figure l shows the invention incross-sectional elevation in position. Fig. 2 is a top view of the bung.'Fig. 3 is an elevation of the recess in the bung. Fig. 4 is anelevation of the bushing. Fig. 5 is an elevation of the stopper, andFig. 6 is a top view of the bush- Like letters indicate likeparts.

The object of the present invention is to provide a bung for barrelsthat is cheap, durable, readily placed 'in position, easily operated inall positions, suitable for venting purposes, and that can be safelylocked. It consists mainly of a bushing and stopper of peculiarconstruction and arrangement, and an interposed washer, allsubstantially as is hereinafter described and shown.

In the drawing, A, Fig. 1, represents a portion of a barrel of ordinaryconstruction, and B the improved bung in position. The bung is mainlycomposed of two parts, viz., a bushing or socket piece, and a stopper.The bushingG, Figs. 1, 2, 4, and 6, in its general shape is tubular, andis composed of any suitable metal. It is provided on its outside with athread. It is of any desirable diameter, and its length by preference isabout the thickness of the stave in which it is inserted. On its inside,at its outer end, it is also provided with a thread. Just below theposition of this last mentioned thread, or thereabout, the bushing isprovided with an inwardly-pro` jecting iiange or ledge, D, Figs. 1 and6, that preferably extends around the inside of the bushing, and is, onits inside, furnished with shoulders d d1 cl2 d3 d4 d5, of any suitablenumber or inclination. The bushing is also provided at its upper endwith an outwardly-projecting flange, e, which, on its under side, ispreferably concave, and shaped so as to elnbed slightly in the stave asthe bushing is fastened in place. E, Figs. 1., 2, and 5, repprovided onits outside with a thread to enable it to be screwed into the bushing C.The thickness of the .stopper is about equal to the depth of the insidethread of the bushing. In the top of theV stopper there is a depression,F, that in its general form is annularthat is, it is a depressionextending around the stopits inner side as to leave in the center aprolt hl, 85e., and which may be of any suitable shape.

In operation, a wrench, of shape similar to that of the projection H, ispassed over the projection, and, by turning the wrench, the stopper isinserted or withdrawn. This part may be operated by a screw-driver, ifpre- I, issuitably cut in its top.

In Fig. 1., J represents an elastic washer that restsv upon the ledge Dand underneath the stopper E. The bushing is screwed into the stave bymeans of a key of suitable shape that is inserted into the openingformed by the ledge 1).' lf preferred, the wrench that is used tooperate the stopper may be suitably shaped on its outside to form apkeyto operate the bushing with. The washer J is then placed on the ledgel), and the stopper screwed down.

A special advantage resulting from the use of the depression in the topof the stopper,

key, is that the bung can be reached and operated when the barrel orkegA is stowed away between shelves. As the bung, by loosening thestopper, can be usedas a vent-hole, and as, in use, .the venting' has tobe done when the keg is in an inconvenient place Afor using any toollike a screw-driver, this advantage is more apparent.

To aid in the venting the stopper is made slightly taperin To enable thebung to be sealed it is on top provided with a dovetailed recess, K,Fig. 2, which -enters partly into the bushing, and partly into thestopper.
